Putting 85% lean Beef (85% lean) in context: it lands well below the category average of 6 mg. In the database, 89% of meat & poultry (68 of 76) fall in the 🟢 Safe group (under 25 mg oxalate/serving). The typical meat & poultry here averages 6 mg oxalate per serving, so 85% lean Beef (85% lean) runs 100% below that baseline. That places it among the lower-oxalate options in its category. Why this matters: the gap between two Safe foods can be wide — one may hold 5 mg oxalate while another sits at 24 mg. The lower one leaves more room in your day.

Why does the safe threshold matter?
The 25 mg cutoff comes from clinical guidance for stone formers. Below it, a food's oxalate contribution is small enough not to move the needle for most patients. Harvard's 2024 lab data sits behind these figures — direct measurements, not estimates. 85% lean Beef (85% lean) comes in at 0 mg oxalate per 3 oz (Safe) in the measured database.
Can I eat this food every day?
Daily eating is fine for Safe foods (under 25 mg/serving). For Caution or Avoid foods, spread them out and alternate with low-oxalate picks. The idea is keeping your weekly oxalate load manageable, not eliminating any single food. For context, 85% lean Beef (85% lean) measures 0 mg per 3 oz, rated Safe.
Where does the oxalate data come from?
The numbers come from Harvard T.H. Chan SPH's 2024 laboratory measurements, published through the OHF database. Direct lab analysis, which is why they're treated as the reference values for food oxalate. For 85% lean Beef (85% lean), the measured oxalate value is 0 mg per 3 oz (Safe).
Should I also check sodium and calcium?
Yes — kidney stone risk isn't just about oxalate. High sodium increases urinary calcium (a stone promoter). Adequate dietary calcium (from food, not supplements) actually binds oxalate in your gut.
